Operation normal for $JD here too and pulling back with the HSI and $BABA, the timing of this coincides with their $1.75 Billion public offering updated today, which may have been a stroke of genius to release this on the same day the HSI was pulling back anyway.
I believe this pulls back to Wave 4 as shown.
The public offering is to help with expansion for overseas expansion, usually a nice soundbyte but if they contribute to their growth, it is money worth diluting for.
